EDMUND WISEMAN AND JOHN HOLROYD, OF LUTON, ENGLAND.

HYDROCARBON-MOTOR.

SPECIFICATION forming part of Letters Patent No. 600,107, dated March 1,1898.

Application filed May 27, 1897.

To all whom it may concern.-

Be it known that we, EDMUND WISEMAN and JOHN HOLROYD, subjects of theQueen of Great Britain, residing at Oheapside, Luton, in the county ofBedford, England, have invented certain new and usefulHydrocarbon-Motors, of which the following is a specification. r

The objects of this invention are to obtain a more perfect mixing,heating, and combustion of the charge, the prevention of fouling, a moreregular supply of the hydrocarbon, and a ready means for starting theengine.

Figure 1 is a central longitudinal vertical section, Fig. 2 a transversevertical section on the line 22, Figs. 1 and ,3, and Fig. 3 a plan, ofso much of a motor as is necessaryto illustrate this invention. Fig. 4isa vertical longitudinal section, and Fig. 5 an end elevation, of theoil-supply apparatus. Fig. 6 is a side elevation, and Fig. 7 an underside view, of the lamp or burner Z. Figs.'8 to 11 show a modification.Fig. Sis a side elevation, and Fig. 9 a plan. Fig. 10 is a section onthe line 10 10, Figs. 8 and 9; and Fig. 11 is a horizontal section onthe line 11 11, Fig. 10.

a is the cylinder, carried on the hollow bed I), which forms anair-reservoir.

b is a pipe passing through the reservoir I), having an air-admissionvalve 19 at its lower end and a branch pipe 19 near its middle, with anemission-valve 6 leading into the reservoir b.

' a. a a a are annular passages formed in the walls of the end of thecylinder.

0 is a pipe opening into the reservoir Z2 and having two branches. 0 0leading, respectively, into the annular passages a and a d is a pipeleading from the annular passage a to the end of the pipe 0, whose otherend is open to the cylinder, and f is a valve between the two pipes.

g is a pipe leading from the annular passage 0t to the pipe (1, justbelow the valve f, and h is a valve on the pipe 9.

j is a casting on the top of the cylinder at and having within it acircuitous passage j, having its ends connected to the annular passagesa and a is is the oil-supply apparatus. (Shown to a larger scale atFigs. 4 and 5.)

Air from the reservoir 12 is led by the pipe 0 to the annular passage a,in which it becomes heated, and then enters the circuitous passage j, atthe commencement of which it meets with the oildelivered by the measurerk. The oil and air pass together through the circuitous passage j, theannular passage 01?, and pipe to the valve f, the vaporization of theoil being completed in traversing these hot passages. At the Valve f thehot mixture of air and vapor meets a supply of air led from thereservoir b by the pipe 0 into the annular passages a a in which itbecomes heated and from whence it is conducted by the pipe (1 to thevalve f. Z is' the lamp. Figs. 6 and 7.)

m is the exhaust-port, leading to a chamber in which there is anexhaust-valve n and an air-admission valve 0. The valve n is opened oncein every two revolutions of the crankshaft by any ordinary gearing,which is not shown. The valve 71. is operated by the governor in theusual way, so that the supply of hyrdocarbon vapor is stopped when theengine is running too fast. The valves f and o are operated by thesuction of the piston; but they may also be aoted'on by the governor toprevent the cooling of the engine when running light.

In Figs. 4 and 5, 7c is a reservoir having within it a conical shellthrough which are two diametrically opposite horizontal holes, oneleading into the reservoir and the other to the air-pipe 70 and also twovertical holes, one leading to the bottom of the air-pipe it, connectedto the reservoir 6, and the other to the top of the pipe is, leadinginto the passage j, Fig. 1. k is a solid conical plug in the shell k andhaving a hole passing diametrically through it, alternately connecting70 with 70 (Shown to a larger scale at when the oil enters it and 71:with 16 when the oil is sucked out of it by the outstroke of the piston.Wis a spindle fixed to the plug 716 and carrying a pinion or quadrant kgearing with a pinion or quadrant it", to which an oscillating motion isgiven by means not shown. 10 is a collar fixed to the spindle is, and 70a collar loose on it. 10 is a spring tending to force the collars 10 andZ0 apart, and so keep the plug 10 tight in the shell k 70 is a screwcapclosing the end of the shell k and 70 is a hole admitting air to the topof the reservoir 7a.

In the lamp or burner shown at Figs. 6 and 7, Z is the base-plate,screwing onto the top of the pipe 6, Fig. 1, and Z is a passage formedin it which is connected to an oil-supply pipe Z and to the nozzle Z isa regulating-needle in the nozzle. Z is a tube fixed to the baseplate,and Z is a diaphragm of wiregauze in it.

In starting the engine the axial pipe or annular ohamber,or both,areheated in any convenient manner, and then as soon as the hydrocarbon inthe passage Z vaporizes the burner lmay be ignited to assist in theheating of the engine, so as to obtain an earlier start. It is also usedto maintain the heat of the engine when running light or duringstoppages. In ordinary work, however, the engine is selfiigniting. Thelamp Z may either be fixed to r the top of the axial pipe, as shown, orto the bottom.

The engine shown is designed to work with a four-stroke cycle, theinstroke of the piston after an explosion sweeping out the products ofcombustion through the exhaust-port m and valve 77., which isautomatically opened at this time. The ensuing outstroke draws in aheated mixture of hydrocarbon vapor and air through the valve f and ofair through the valve 0. The next instroke compresses the charge, whichautomatically ignites and so completes the cycle. Some of theimprovements are, however, applicable to engines working with othercycles. The reservoir 1) may also be dispensed with and the engine bemade with an open-ended cylinder. In this case the pipe M, Fig. 4, isopen to the outer air.

In the modification shown at Figs. 8 to 11 the annular passages a, 0.and a for heating the air are replaced by other ordinary means, and theblock or casting j, containing the circuitous passage j, is brought intodirect contact with the cylinder. In this case the air heated by theexhaust or otherwise is admitted at f directly to the valve f, while theoil (and, it may be, some air also) is led by the pipe from the nozzle70 of the measurer, Figs. 4: and 5, which is not shown, into thecircuitous passage j and from thence passes by the annular passage ainto the pipe 9, made in one piece with the pipe 6, to the valves h andf and so to the cylinder.
